Brief summary: Using a combination of expression studies in human embryos as well as functional studies in zebrafish and genetic sequencing of patient with congenital hypogonadotropic hypogonadism, this study identified a novel role for Jag1/Notch signaling in the development of GnRH neurons.GnRH neurons have a unique characteristic as they start life in the olfactory placode and then migrate into the hypothalamus during embryonic development, thanks to ...

Brief Summary: This study examined the incidence and risk factors for adrenal crisis (AC) in patients with pediatric-onset adrenal insufficiency (AI). AC occurs in a substantial number of children with AI, particularly in younger children due to their high number of infections.Comment: Adrenal crisis (AC) is a life-threatening complication in patients with adrenal insufficiency (AI) (1-4). The clinical features of AC are often nonspecific, and it may be ...
